Hamill was recently spotted at JFK airport in New York, hunched over in a wheelchair, leading fans to speculation about his health. However, the actor has now confirmed that he is fit and well, and was using the wheelchair as part of a disguise to avoid unscrupulous autograph-hunters.

“When filming [the] scene I was assured my lightsaber swipe toward camera (creature not on set) would simply singe fur to scare him off,” Hamill tweeted. “[I was] horrified to later see amputation and unnecessary cruelty. Wampa was HUNGRY (not EVIL). Luke would never do this!”
